Much House Can I Afford Calculator

Use this How Much House Can I Afford Calculator to estimate the maximum home price and mortgage that may fit your income, down payment, interest rate, monthly debts and housing expenses. Choose Canada or the United States, enter your financial information, and the calculator will estimate your home-buying range along with the mortgage payment, property taxes, insurance, debt ratios and total monthly housing cost.

Mortgage qualification and true household affordability are not always the same thing. A lender may calculate how much you qualify to borrow using gross income and debt ratios, while your personal budget also needs to cover food, transportation, savings, repairs, childcare, utilities and other expenses. This calculator gives you a detailed starting point so you can test different incomes, down payments, mortgage rates and monthly costs before shopping for a home.

How to Use the How Much House Can I Afford Calculator

Start by selecting Canada or the United States. Mortgage qualification rules are not identical in the two countries, so the calculator changes its assumptions and calculations depending on the country selected.

Enter your total gross household income before tax. If two people will apply for the mortgage together, enter the combined qualifying income you expect the lender to consider. Next, enter the cash you have available for your down payment. Do not include money that you need to keep aside for closing costs, emergency savings, moving expenses or immediate repairs.

Enter the expected mortgage interest rate and choose the amortization or loan term. The calculator uses this rate to estimate the actual monthly mortgage payment. In Canada mode, the calculator can also apply the mortgage stress test and calculate a separate payment using the higher qualifying rate.

Add your monthly debt payments. Include recurring obligations such as car loans, student loans, minimum credit-card payments, lines of credit and other debts that a lender may consider when evaluating your application.

Simple mode uses built-in assumptions for property taxes, insurance, heating or utilities and qualification ratios. Advanced mode allows you to replace those assumptions with numbers that more closely match the home, city and mortgage product you are considering.

The main result is an estimated maximum home price. The calculator also displays the mortgage amount, estimated monthly mortgage payment, total monthly housing cost, down-payment percentage and applicable debt ratios.

After finding an estimated purchase price, use the Mortgage Calculator to test a specific mortgage amount and view a detailed amortization schedule.

How Much House Can I Afford?

The amount of house you can afford depends on several financial variables working together rather than one simple salary multiple. Your income matters, but so do the size of your down payment, current mortgage rates, other debts, property taxes, insurance, utilities and the length of the mortgage.

Two households earning exactly the same salary may have very different home-buying power. One household may have no debt and a large down payment, while another may have two vehicle loans, student debt and only a small down payment. Their gross incomes are identical, but the amount available for housing is not.

Interest rates also make a major difference. A mortgage that fits comfortably within a debt ratio at one rate may exceed the same ratio after rates rise. Because affordability is based partly on the monthly payment, a higher interest rate generally reduces the mortgage principal that can be supported by the same income.

This is why a useful house affordability calculator works backward. Instead of starting with a home price and telling you the payment, it starts with your income and expense limits, calculates how much monthly mortgage payment fits inside them, and then converts that payment into an estimated mortgage and home price.

How Income Affects How Much House You Can Afford

Mortgage qualification calculations usually begin with gross income rather than take-home income. Gross income means earnings before income tax, payroll deductions and many other amounts are removed.

If your annual household income is $120,000, gross monthly income is $10,000. A lender can then compare required housing expenses and total debt obligations with that $10,000 figure.

Higher qualifying income generally supports a larger mortgage because a larger monthly payment can remain inside the same debt-ratio percentage. However, increasing income does not automatically solve every affordability constraint. A small down payment may still limit the purchase price, particularly where minimum-down-payment rules apply.

Income can also be treated differently depending on how it is earned. Salaried income may be straightforward, while overtime, bonuses, commissions, self-employment income, rental income and recently increased income can require documentation or averaging under lender policies.

The calculator assumes the annual income entered is the amount that will be accepted for qualification. If you are unsure what portion of variable income a lender will use, run several scenarios rather than assuming every dollar will automatically qualify.

If you want to compare gross salary with estimated take-home earnings, use the Paycheck Calculator. That can help with the separate question of whether a mortgage payment fits your monthly cash flow after deductions.

How a Down Payment Changes Home Affordability

Your down payment affects affordability in more than one way. First, every dollar you contribute directly reduces the amount that needs to be borrowed. Second, a larger down-payment percentage can reduce or eliminate mortgage-insurance costs. Third, minimum-down-payment requirements can place a hard limit on how expensive a property you can purchase even when your income could theoretically support a larger mortgage.

Suppose one buyer has $25,000 available and another has $100,000. Even if they earn the same income, the second buyer may be able to purchase a more expensive home because less borrowing is required and a greater range of properties meets the applicable equity rules.

A larger down payment also lowers the loan-to-value ratio. Loan-to-value, often abbreviated LTV, compares the mortgage amount with the property’s value. A $400,000 mortgage on a $500,000 home has an 80% loan-to-value ratio before considering any financed mortgage-insurance premium.

There is a trade-off. Putting every available dollar into the down payment may produce a smaller mortgage, but new homeowners also need cash for legal fees, moving, furnishings, repairs and emergencies. The maximum down payment you could make is not necessarily the amount you should use.

How Mortgage Interest Rates Affect How Much House You Can Afford

Mortgage rates have a direct effect on purchasing power because the same mortgage principal creates a different monthly payment at different interest rates.

When rates fall, more of a fixed monthly payment can go toward principal and a larger mortgage can often fit within the same income-based limit. When rates rise, more of each payment is required to cover interest, reducing the principal amount supported by that payment.

This effect can be substantial over a long amortization period. A buyer should therefore avoid using a rate that is dramatically lower than the rate they realistically expect to receive. A small change in the input can move the estimated maximum home price by tens of thousands of dollars or more.

It can be useful to calculate three scenarios: a lower rate, your expected rate and a rate one percentage point higher. This shows how sensitive the budget is to financing conditions.

If you already know the mortgage amount and want to isolate exactly how the rate changes the monthly payment, use the Mortgage Estimate Calculator.

How Monthly Debt Payments Reduce Home Affordability

Income is only one side of a mortgage qualification calculation. Existing debt payments can reduce the amount of monthly income available for a new housing payment.

Examples can include vehicle loans, student loans, credit-card minimum payments, unsecured loans, lines of credit and other recurring obligations. The exact treatment can vary by lender, but the general principle is simple: money already committed to debt cannot also be used to support the new mortgage payment.

Imagine two households that each earn $10,000 gross per month. One has no monthly debt. The other has $1,500 of vehicle and loan payments. If the lender limits total debt to the same percentage of income for both households, the second household has roughly $1,500 less room before reaching that limit.

This is one reason paying off a relatively large monthly debt can sometimes improve mortgage qualification more than simply adding the same dollar amount to the down payment.

How Much House Can I Afford in Canada?

Canadian mortgage affordability calculations commonly use Gross Debt Service and Total Debt Service ratios. They also need to account for the mortgage qualifying rate, often called the mortgage stress test.

In Canada mode, this calculator uses GDS and TDS as separate constraints. The estimated home price is increased until one of the limits is reached. This is more realistic than simply multiplying annual income by an arbitrary number.

Canadian mortgage payments are also calculated using a semi-annual compounding convention converted to an equivalent monthly rate rather than assuming the simple nominal-rate-divided-by-12 method commonly used for U.S. mortgages.

The Canada calculation also checks whether the available down payment meets current minimum-down-payment rules and estimates the mortgage-insurance premium when the down payment is below 20% and the property is eligible for insured financing.

What Is the GDS Ratio?

GDS stands for Gross Debt Service. It measures qualifying housing expenses as a percentage of gross household income.

For a Canadian mortgage, housing costs generally include the qualifying mortgage payment, property taxes, heating and a portion of condo fees where applicable.

This calculator defaults to a maximum GDS ratio of 39% in Canada mode. Because underwriting policies can vary and individual applications may be assessed differently, Advanced mode allows the percentage to be changed.

For example, if gross household income is $10,000 per month, 39% equals $3,900. The qualifying mortgage payment plus relevant housing expenses would need to fit within that amount under a 39% GDS assumption.

What Is the TDS Ratio?

TDS stands for Total Debt Service. It begins with the housing expenses included in GDS and then adds other debt obligations.

The calculator defaults to a 44% TDS limit in Canada mode. That means total qualifying housing costs and recurring debt payments together are limited to 44% of the gross monthly income in the model.

If a borrower has very little outside debt, GDS may be the limiting factor. If the borrower has large vehicle, credit-card or student-loan payments, TDS may become the tighter constraint.

Canadian Mortgage Stress Test

The Canadian mortgage stress test qualifies borrowers using a rate that is higher than the contract rate. In the calculator, the default qualifying rate is the greater of the mortgage contract rate plus two percentage points or 5.25%.

For example, if the actual mortgage rate is 4.25%, adding two percentage points gives 6.25%. Since 6.25% is higher than 5.25%, the calculator uses 6.25% as the qualifying rate.

If the contract rate were 2.75%, adding two points would produce 4.75%. In that example, the 5.25% floor would be higher, so the qualifying rate would be 5.25%.

The qualifying payment is used to test the debt ratios, while the result section separately shows the estimated actual monthly payment at the mortgage rate you entered. That distinction is important: the payment used to qualify can be higher than the payment you initially make.

The current minimum qualifying rate framework for federally regulated uninsured mortgages is published by the Office of the Superintendent of Financial Institutions.

Minimum Down Payment in Canada

Canada’s minimum down payment depends on the purchase price. For homes priced at $500,000 or less, the minimum is generally 5% of the purchase price.

For an eligible home above $500,000 but below $1.5 million, the minimum is 5% of the first $500,000 plus 10% of the portion above $500,000.

At $1.5 million or more, a minimum 20% down payment is required under the federal framework used by this calculator.

Example: Minimum Down Payment on a $600,000 Home

The first $500,000 requires 5%, which is $25,000. The remaining $100,000 requires 10%, which is another $10,000. The minimum down payment is therefore $35,000.

Example: Minimum Down Payment on a $1,000,000 Home

The first $500,000 requires $25,000. The remaining $500,000 requires $50,000. The total minimum down payment is therefore $75,000.

You can review the federal rules directly through the Financial Consumer Agency of Canada.

Mortgage Loan Insurance and Home Affordability

A Canadian mortgage with less than 20% down will typically require mortgage loan insurance when the property and borrower meet the applicable requirements.

The insurance premium is calculated as a percentage of the insured loan amount. A higher loan-to-value ratio generally produces a higher premium rate. The premium can typically be added to the mortgage principal, which means the borrower then makes mortgage payments on the original borrowed amount plus the financed premium.

The calculator estimates the standard CMHC-style premium according to the loan-to-value range. For a standard insured mortgage, rates used by the calculator are 2.80% for an LTV above 80% through 85%, 3.10% above 85% through 90%, and 4.00% above 90% through 95%.

For an eligible 30-year insured mortgage, the calculator adds the current 0.20 percentage-point Home Start premium surcharge. This produces rates of 3.00%, 3.30% and 4.20% across the corresponding high-ratio ranges.

Actual mortgage-insurance eligibility and premium amounts can depend on the mortgage product and borrower. Provincial sales tax on insurance premiums, where applicable, is not included in the financed mortgage estimate.

30-Year Mortgages in Canada

A longer amortization reduces the required monthly mortgage payment because repayment is spread across more months. That can increase the mortgage amount that fits inside a particular debt-service ratio.

It also means interest can accrue over a longer period. A lower payment does not mean the mortgage is cheaper overall.

Under Canada’s current insured-mortgage rules, eligible first-time buyers and buyers of qualifying newly built homes can access 30-year insured amortizations. Uninsured mortgages may also have different amortization options depending on the lender and product.

If you want to compare the long-term interest difference between amortization periods, use the Mortgage Interest Paid Over Time Calculator.

How Much House Can I Afford in the United States?

The U.S. side of the calculator uses debt-to-income ratios to estimate the mortgage payment that fits within the assumptions you select.

Unlike Canada’s standardized GDS and TDS framework used for insured-mortgage calculations, U.S. DTI requirements vary by lender and mortgage program. Conventional mortgages, FHA loans, VA loans and other products can have different underwriting standards.

Simple mode uses a 28% housing ratio and 36% total-debt ratio as planning assumptions, but these numbers should not be interpreted as universal approval limits. Advanced mode lets you replace them with the numbers you want to model.

U.S. housing expenses in the calculator include mortgage principal and interest, property taxes, homeowners insurance, HOA fees and any monthly PMI amount entered.

What Is Debt-to-Income Ratio?

Debt-to-income ratio, or DTI, compares monthly debt payments with gross monthly income.

If a household earns $8,000 per month before tax and has $3,000 of qualifying debt payments, the DTI is 37.5%.

The Consumer Financial Protection Bureau notes that different lenders and loan products have different DTI limits. That is why the calculator exposes the ratio assumptions instead of claiming that one percentage applies to every U.S. borrower.

How Much House Can I Afford Based on My Salary?

Salary-based home affordability searches are common because income is usually the first number buyers know. However, there is no reliable universal answer such as “your house should cost exactly four times your salary.”

The same $100,000 income can support very different home prices depending on the mortgage rate, down payment, taxes and monthly debt.

How Much House Can I Afford on a $60,000 Salary?

A $60,000 annual household income equals $5,000 gross per month. The portion available for housing depends on the debt-ratio limit and other obligations. A buyer with no debt and a large down payment may support a significantly different purchase price than someone earning the same $60,000 but carrying a large vehicle loan.

Enter $60,000 in the calculator and then use your actual down payment, debts, rate and property-cost assumptions rather than relying on a generic salary multiple.

How Much House Can I Afford on an $80,000 Salary?

An $80,000 household income is approximately $6,667 gross per month. The calculator compares qualifying housing expenses and debt payments against that monthly amount. Changing the interest rate by even one percentage point can noticeably change the estimated home price.

How Much House Can I Afford on a $100,000 Salary?

A $100,000 salary produces approximately $8,333 of gross monthly income. Instead of assuming a fixed home-price multiple, the calculator tests how much mortgage payment fits within the selected debt-ratio limits after accounting for taxes, heating, insurance and existing debt.

How Much House Can I Afford on a $120,000 Salary?

A $120,000 annual household income is $10,000 gross per month. That makes it convenient to see how the ratios work. A 39% housing threshold represents $3,900 per month before considering how the individual housing components are allocated.

How Much House Can I Afford on a $150,000 Salary?

A $150,000 annual income equals $12,500 gross monthly. Higher income generally supports a larger housing payment, but affordability can still be constrained by other debt and down-payment rules.

How Much House Can I Afford on a $200,000 Salary?

A $200,000 household income is approximately $16,667 gross per month. At this income level, down-payment requirements can become particularly important if the resulting home price approaches thresholds where insured financing is no longer available.

Costs to Consider Beyond the Mortgage Payment

A mortgage is usually the largest housing expense, but it is not the only cost of owning a home. Looking only at principal and interest can make a house appear substantially cheaper than it really is.

Property Taxes

Property taxes vary dramatically by city and property. The calculator estimates them as a percentage of the home’s value so they increase automatically as the estimated purchase price changes.

If you know the actual annual property tax amount for a property, convert it to an approximate percentage of the property value or use a more specific mortgage calculator once you begin comparing individual listings.

Homeowners Insurance

Insurance protects the property against covered risks and is normally an ongoing cost of homeownership. Rates depend on location, building type, coverage, deductibles and other factors.

Heating and Utilities

Heating costs can vary significantly with climate, home size, insulation, heating system and energy prices. Canadian GDS calculations specifically make heating expenses important to the qualification estimate.

Condo or HOA Fees

A condominium or homeowners association can add hundreds of dollars per month. In Canada mode, the qualification calculation uses 50% of the entered condo fee in the modeled GDS/TDS housing expense, while the full fee is included when displaying estimated actual monthly housing cost.

Maintenance and Repairs

The qualification estimate does not automatically deduct a maintenance budget because lender affordability ratios generally do not treat normal future maintenance like a contractual debt payment. Your personal budget should still account for it.

Roofs, furnaces, appliances, plumbing, landscaping and unexpected repairs can create irregular but significant expenses. A household that spends every available dollar on the required mortgage payment may have little flexibility when these costs appear.

Closing Costs

The down-payment input should not include money you need for closing costs. Depending on the location and transaction, these can include legal fees, title costs, inspections, appraisals, land-transfer taxes or recording fees and adjustments for prepaid property expenses.

How Much You Qualify For vs. How Much You Can Comfortably Afford

A mortgage qualification calculation answers a specific lending question: how large a payment fits within the lender’s underwriting rules based on the income, debts and housing expenses they recognize.

Your personal definition of affordable may be much lower.

Debt-service and DTI formulas do not know how much you spend on groceries, childcare, vacations, fuel, retirement savings, hobbies, medical expenses, family support or other lifestyle costs that may be important to you.

A household may technically qualify for a particular mortgage while deciding that a smaller payment better supports its other financial goals. Conversely, a calculator result is not a guarantee that a lender will approve that amount.

Use the result as a range to investigate rather than a target that must be spent. It can be useful to run the calculator at several home prices below the maximum and compare what happens to the monthly cost and remaining cash flow.

Should I Buy the Maximum House I Qualify For?

The maximum qualifying amount represents the upper end of the assumptions entered into the calculator. It does not account for every personal goal or unexpected expense.

Before choosing a purchase price, consider how the payment would affect emergency savings, retirement contributions, vehicle replacement, travel, childcare and other priorities.

Also consider whether you would still be comfortable with the payment if property taxes, insurance, utilities or maintenance costs increased.

If you are deciding whether buying at a particular price is financially better than continuing to rent, the Rent vs Buy Calculator compares homeownership with renting over time.

How to Increase Home-Buying Affordability

The calculator makes it easy to see which variables have the greatest impact on your estimate. Change one input at a time to see the effect.

• Increase the down payment: A larger down payment reduces the amount borrowed and may reduce mortgage-insurance costs.
• Reduce monthly debt: Paying off a vehicle loan or other payment can create more room under the total debt ratio.
• Increase qualifying income: Higher documented household income increases the denominator in debt-ratio calculations.
• Find a lower mortgage rate: A lower rate reduces the payment required for a given principal balance.
• Choose a longer amortization where eligible: Spreading repayment across more years reduces the scheduled payment, although it can increase total interest.
• Choose a lower-tax property: Property tax is part of the housing expense and can affect qualification.
• Reduce condo or HOA fees: Recurring property fees increase the monthly housing cost.

Why Property Taxes Change Mortgage Affordability

Property taxes are sometimes overlooked because they are not part of the mortgage principal. From an affordability perspective, however, they still consume monthly cash flow and may be included in lender qualification calculations.

Two homes with the same purchase price and mortgage can therefore have different affordability results if their property-tax obligations differ substantially.

The calculator estimates taxes as a percentage of property value because the home price itself is being solved dynamically. If the assumed tax rate is 1%, a $500,000 home creates an estimated $5,000 annual tax bill or roughly $417 per month.

How Condo Fees Affect Home Affordability

Condo fees can significantly change affordability because they are recurring expenses that remain even after the mortgage is eventually paid off.

When comparing a condo with a detached house, do not compare the mortgage payments alone. A condo with a $500 monthly fee may need to be evaluated differently from a similarly priced house without one.

Some condo fees cover costs that a detached homeowner would otherwise pay separately, such as exterior maintenance, building insurance or common utilities. Others primarily fund amenities and building operations. The financial effect depends on what is included.

Mortgage Affordability Calculator vs. Mortgage Payment Calculator

A mortgage payment calculator starts with a mortgage amount and calculates the payment. A mortgage affordability calculator works in the opposite direction.

With a payment calculator, you might enter a $500,000 mortgage and ask what the monthly payment will be. With an affordability calculator, you enter income, debts and expenses and ask what mortgage amount those numbers may support.

Both calculations are useful at different stages. Early in the home search, affordability helps establish a price range. Once you start evaluating specific properties, payment and amortization calculators become more useful.

How Much Mortgage Can I Afford?

The mortgage amount and the home price are not the same. The home price includes the money supplied by your down payment, while the mortgage finances the remainder and may also include a financed mortgage-insurance premium.

If a home costs $500,000 and you contribute $100,000, the base mortgage is $400,000. If mortgage insurance is not required, the mortgage principal begins at approximately $400,000 before any other financed items.

If the down payment is smaller and mortgage insurance is required, the insurance premium may be added to the mortgage principal. That means the financed mortgage can be slightly larger than purchase price minus down payment.

How Much Home Can I Afford With No Debt?

Having no recurring debt can materially increase mortgage qualification because the total-debt ratio has more room available for housing expenses.

However, zero debt does not automatically mean the entire total-debt allowance can be used for mortgage principal. Property taxes, utilities, insurance and condo or HOA fees still consume part of the housing budget.

In Canada, GDS can also become the binding limit even when TDS has plenty of room. That prevents a debt-free borrower from automatically using the entire TDS percentage for housing.

How Much House Can Two Incomes Afford?

When two borrowers apply together and both incomes are accepted by the lender, the calculator can model them by adding the annual gross incomes together.

For example, if one borrower earns $70,000 and the other earns $50,000, enter $120,000 as household income.

Remember to combine the debts as well. If one person has a $600 monthly vehicle payment and the other has a $300 student-loan payment, enter $900 of monthly debt rather than only one borrower’s obligations.

Does Credit Score Change How Much House I Can Afford?

Credit score is not directly included as a numerical input in this calculator because its effect is not a simple universal formula.

Credit can affect whether you qualify, the loan programs available to you and potentially the rate or pricing you receive. Since interest rate directly affects mortgage affordability, credit can indirectly change the amount of home that fits your budget.

If a weaker credit profile results in a higher mortgage rate, enter the higher expected rate in the calculator rather than relying on an advertised rate that you may not receive.

How Closing Costs Affect What You Can Buy

The calculator assumes that the entire down-payment amount entered is available exclusively for the down payment. In real life, buying a home also requires cash for closing.

If you have $75,000 saved but expect to need $15,000 for closing costs and immediate expenses, you may want to enter $60,000 as the down payment rather than $75,000.

This prevents the affordability estimate from assuming that cash needed elsewhere will be applied to the purchase price.

How Amortization Changes Home Affordability

A longer amortization lowers the required payment for the same mortgage amount. Because lenders evaluate the payment rather than merely the principal balance, a longer amortization can increase the mortgage that fits within a debt ratio.

The trade-off is total interest. A borrower who repays a mortgage over 30 years instead of 20 years can make a substantially larger number of interest-bearing payments.

That makes amortization a useful affordability tool but not a free reduction in cost. Compare both monthly payment and lifetime interest before making a decision.

How to Compare Different Home Prices

Once the calculator provides an estimated maximum, consider testing several lower prices rather than looking only at the top number.

For example, if the result is $650,000, compare $550,000, $600,000 and $650,000 in a mortgage payment calculator. Look at the difference in monthly mortgage payments, interest, property tax and required down payment.

You can also use the Percentage Calculator when comparing down-payment percentages, price changes or percentage differences between two homes.

Why Your Lender’s Number May Be Different

No online affordability calculator can reproduce every lender’s underwriting system. A lender may calculate income differently, use a different tax estimate, require a different heating amount, calculate debt payments according to internal guidelines or apply additional rules based on credit and property type.

Variable income is a common source of differences. Overtime, bonuses, commissions and self-employment income may require a history before all of it can be included.

The property itself can also matter. A lender may use the actual property tax and condo fees associated with the home being purchased rather than the general assumptions entered into a calculator.

Treat the result as an estimate for planning and comparison, not a promise of mortgage approval.

How Much House Can I Afford Calculator Frequently Asked Questions

Final Thoughts

The question “how much house can I afford?” cannot be answered accurately from salary alone. Home affordability is the result of income, debt, down payment, mortgage rates, amortization, taxes, insurance, utilities and other housing expenses working together.

Use Canada mode to estimate affordability with GDS, TDS, minimum-down-payment rules, mortgage insurance and the Canadian mortgage stress test. Use United States mode to model housing and total debt-to-income ratios while adjusting the limits to match the mortgage program or lender you are considering.

Once you have an estimated maximum home price, run several lower-price scenarios as well. Comparing payments at different price levels can be more useful than focusing entirely on the largest mortgage you may qualify to borrow. The goal of the calculator is to give you a realistic range to investigate before you move on to specific listings, mortgage quotes and lender approval.
